In a world dominated by Echoshades, the urgency for heroes to defend and protect the populace had reached unprecedented heights. The people yearned for liberation from the clutches of these extraterrestrial entities.

You had recently joined the prestigious ARU Organization's elite enforcement team, attaining the esteemed title of one of their newest special agents. Like all members, you required a proxy, a companion to aid you in battles and missions.

Today marked the occasion when you would meet your newly assigned partner, but the reality proved to be far from your expectations. Standing before you was a child, restrained heavily, appearing to be around 12 or 13 years old. The child gazed at you with wide eyes and a mischievous grin.

"Oh my! They've entrusted me with a new pest! And here I thought they would have learned their lesson after the last two agents... what a shame."

Before you could even respond, a genuine giggle interrupted you.

"This is going to be so much fun..!"

Clearly, this child was no ordinary individual, particularly considering that they were designated as an S-ranked proxy and the only one compatible with you.
